Hazardous Area (Ex) Equipment Awareness
Why plant areas are classified into zones, how explosion-protected (Ex) equipment is built and marked, and the everyday disciplines — never opening energised Ex enclosures, keeping bolts and glands intact, inspection grades and the Ex register — that keep an installation safe. For technicians, operators, engineers and supervisors working in or around flammable atmospheres.

Ce que vous apprendrez
- Explain why areas are classified: flammable atmospheres, sources of release and the ignition sources we control
- Identify Zone 0, Zone 1 and Zone 2 for gases and give typical plant examples of each
- Describe gas groups (IIA/IIB/IIC) and temperature classes (T1–T6) and why substituting a lower group or T class is unsafe
- Explain the common protection concepts — Ex d, Ex e, Ex i and Ex n — where each is typically used, and how to read an Ex marking string to confirm equipment suits its zone
- Apply the field rules: never open energised Ex equipment in a hazardous area, keep every bolt and gland intact, distinguish visual, close and detailed inspection grades, and report findings
- Describe what an Ex register must record and recognise unauthorised modification as the classic route to a non-compliant installation
